svuint64_t svdot[_u64](svuint64_t op1, svuint16_t op2, svuint16_t op3)

128-bit SVE

For each group of four unsigned 16-bit integers from (1) and (2), compute the dot-product, then add the result to the corresponding 64-bit integer accumulator from (3), setting (4) to the total.

256-bit SVE

For each group of four unsigned 16-bit integers from (1) and (2), compute the dot-product, then add the result to the corresponding 64-bit integer accumulator from (3), setting (4) to the total.

512-bit SVE

For each group of four unsigned 16-bit integers from (1) and (2), compute the dot-product, then add the result to the corresponding 64-bit integer accumulator from (3), setting (4) to the total.
